No. As far as the money is concerned it is no different.Precisely, which is why I disagreed when you said it was no different than selling a detached property. Chalk and cheese.
So what happened when you wanted to sell and it was discovered the roof needed replacing?And no, it definitely doesn't apply to all flats. I have lived in flats where residents were completely responsible for maintaining them, internally and externally. Usually smaller blocks.
And what difference would there have been had it been a house?
